Title: Fuel injection systems
IPC: F02D3/02
Filed: 1974-03-15
Abstract: 1466787 Fuel injection systems ROBERT BOSCH GmbH 15 March 1974 [16 March 1973]  11559/74 Heading F1B A fuel injection system for spark ignition I. C. engines having continuous injection into the intake manifold comprises a fuel pump 16 arranged to deliver fuel to a fuel injection quantity regulating device 8 operable in dependence upon the air-flow rate through the engine intake manifold 3, a first pressure regulator 30 which determines the pressure of fuel in part of the system in normal operation, fuel injection nozzles 27 whose opening pressure is below this normal pressure in said part of the system, and a second pressure regulator 38, activated when the fuel pump is activated to maintain the pressure of fuel in said part of the system below the nozzle opening pressure but substantially above the vapour pressure of the fuel at 100‹C for a predetermined time. This allows fuel which has leaked or evaporated from the system to be replenished. The second pressure regulator 38 is connected in series with a solenoid operated valve 41, which is kept open by a time switch 42, to a line 29 upstream of regulator 30 or a line 34 leading from the device 8 to a pressure control valve 35 which varies the control pressure in a pressure chamber 36 in dependence on engine operating characteristics. This control pressure is less than the pressure of fuel supplied to device 8 because of the presence of a valve 37. An operating magnet 44, which may be combined with solenoid operated valve 41, is operated when time switch 42 is closed, to act via lever 10 on control valve spool 12 to open a path to ports 24 so that the lines 26 leading to the nozzles 27 are filled. Alternatively, instead of the operating magnet 44, lines (47), Fig. 2 (not shown), with non-return valves (49) may supply fuel from line (48) joining the solenoid valve 41 to the pressure regulator 38 to the lines 26. In another embodiment, Fig. 3 (not shown), a reservoir (50) is connected by way of a non-return valve (52) and a throttle (51) to the line 18 from the fuel pump 16 to the device 8.

Patent GB-714163-A (GB)
Title: Improvements in or relating to the preparation of organic acid esters of cellulose
IPC: C08B1/02
Filed: 1951-05-18
Abstract: Fibrous cellulose having a water-content below 15 per cent. is conditioned, so as to render it more suitable for esterification, by adding water to it to raise the water-content above 15 per cent., and then removing at least 5 per cent. of water, without reducing the water-content of the cellulose below 4.5 per cent. Further, the amount of water present during the conditioning is at no time sufficient to form a continuous liquid phase.  The treatment leads to uniformity in subsequent activation and esterification.  A substantial increase in activity is obtained by raising the moisture content to 90-100 per cent. and then removing at least 80 per cent. of moisture.  The reduction in moisture content is preferably effected by evaporation methods, e.g. by blowing air through the cellulose.  After the conditioning treatment, the cellulose may be given an activating pretreatment with an aliphatic carboxylic acid such as formic, acetic, or propionic acid, if desired in presence of a small proportion of an esterification catalyst such as sulphuric or phosphoric acid. This pretreatment may be carried out in one or more stages.  The subsequent esterification may be effected with an organic acid anhydride, preferably in presence of an esterification catalyst and an organic acid which acts as a solvent for the cellulose ester being formed.  Specifications 665,725, 683,648, 688,580, 706,522 and 709,430 are referred to.
